These can be dealt with by adding\na new kmap_atomic_pte() function for mapping highptes, and hooking it\ninto the paravirt_ops infrastructure.\n\nXen specifically wants to map the pte page RO, so this patch exposes a\nhelper function, kmap_atomic_prot, which maps the page with the\nspecified page protections.\n\nThis also adds a kmap_flush_unused() function to clear out the cached\nkmap mappings. Xen needs this to clear out any potential stray RW\nmappings of pages which will become part of a pagetable.\n\n[ Zach - vmi.c will need some attention after this patch.

One is that vmalloc will update the\nkernel address space mappings, and those updates need to be propagated into\nall processes if the kernel mappings are not intrinsically shared. In the\nnon-PAE case, this is done by maintaining a pgd_list of all processes; this\nlist is used when all process pagetables must be updated. pgd_list is\nthreaded via otherwise unused entries in the page structure for the pgd, which\nmeans that the pgd must be page-sized for this to work.\n\nNormally the PAE pgd is only 4x64 byte entries large, but Xen requires the PAE\npgd to page aligned anyway, so this patch forces the pgd to be page\naligned+sized when the kernel pmd is unshared, to accomodate both these\nrequirements.\n\nAlso, since there may be several distinct kernel pmds (if the user/kernel\nsplit is below 3G), there\u0027s no point in allocating them from a slab cache;\nthey\u0027re just allocated with get_free_page and initialized appropriately. (Of\ncourse the could be cached if there is just a single kernel pmd - which is the\ndefault with a 3G user/kernel split - but it doesn\u0027t seem worthwhile to add\nyet another case into this code).\n\n[ Many thanks to wli for review comments. ]\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Zachary Amsden \u003czach@vmware.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n" }, { "commit": "b239fb2501117bf3aeb4dd6926edd855be92333d", "tree": "62ac25204632ef0b14e3bd84580c722e69800cf7", "parents": [ "3dc494e86d1c93afd4c66385f270899dbfae483d" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Wed May 02 19:27:13 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:13 2007 +0200" }, "message": "[PATCH] i386: PARAVIRT: Hooks to set up initial pagetable\n\nThis patch introduces paravirt_ops hooks to control how the kernel\u0027s\ninitial pagetable is set up.\n\nIn the case of a native boot, the very early bootstrap code creates a\nsimple non-PAE pagetable to map the kernel and physical memory. When\nthe VM subsystem is initialized, it creates a proper pagetable which\nrespects the PAE mode, large pages, etc.\n\nWhen booting under a hypervisor, there are many possibilities for what\npaging environment the hypervisor establishes for the guest kernel, so\nthe constructon of the kernel\u0027s pagetable depends on the hypervisor.\n\nIn the case of Xen, the hypervisor boots the kernel with a fully\nconstructed pagetable, which is already using PAE if necessary. Also,\nXen requires particular care when constructing pagetables to make sure\nall pagetables are always mapped read-only.\n\nIn order to make this easier, kernel\u0027s initial pagetable construction\nhas been changed to only allocate and initialize a pagetable page if\nthere\u0027s no page already present in the pagetable. This allows the Xen\nparavirt backend to make a copy of the hypervisor-provided pagetable,\nallowing the kernel to establish any more mappings it needs while\nkeeping the existing ones.\n\nA slightly subtle point which is worth highlighting here is that Xen\nrequires all kernel mappings to share the same pte_t pages between all\npagetables, so that updating a kernel page\u0027s mapping in one pagetable\nis reflected in all other pagetables. This makes it possible to\nallocate a page and attach it to a pagetable without having to\nexplicitly enumerate that page\u0027s mapping in all pagetables.\n\nAnd:\n\n+From: \"Eric W.

So we need to redo the effort here,\nso we pick up PSE, PGE and the like.\n\nHypervisors like Xen require that their page tables be read-only,\nwhich is slightly incompatible with our low identity mappings, however\nI discussed this with Jeremy he has modified the Xen early set_pte\nfunction to avoid problems in this area.\n\nSigned-off-by: Eric W.

Pte_clear had the same bug,\nso use the same fix for both. Turns out pmd_clear had it as well, but pgds\nare not affected.\n\nThe problem is rather intricate. Page table entries in PAE mode are 64-bits\nwide, but the only atomic 8-byte write operation available in 32-bit mode is\ncmpxchg8b, which is expensive (at least on P4), and thus avoided. But it can\nhappen that the processor may prefetch entries into the TLB in the middle of an\noperation which clears a page table entry. So one must always clear the P-bit\nin the low word of the page table entry first when clearing it.\n\nSince the sequence *ptep \u003d __pte(0) leaves the order of the write dependent on\nthe compiler, it must be coded explicitly as a clear of the low word followed\nby a clear of the high word. Further, there must be a write memory barrier\nhere to enforce proper ordering by the compiler (and, in the future, by the\nprocessor as well).\n\nOn \u003e 4GB memory machines, the implementation of pte_clear for PAE was clearly\ndeficient, as it could leave virtual mappings of physical memory above 4GB\naliased to memory below 4GB in the TLB. The implementation of\nptep_get_and_clear_full has a similar bug, although not nearly as likely to\noccur, since the mappings being cleared are in the process of being destroyed,\nand should never be dereferenced again.\n\nBut, as luck would have it, it is possible to trigger bugs even without ever\ndereferencing these bogus TLB mappings, even if the clear is followed fairly\nsoon after with a TLB flush or invalidation. The problem is that memory above\n4GB may now be aliased into the first 4GB of memory, and in fact, may hit a\nregion of memory with non-memory semantics. These regions include AGP and PCI\nspace. As such, these memory regions are not cached by the processor. This\nintroduces the bug.\n\nThe processor can speculate memory operations, including memory writes, as long\nas they are committed with the proper ordering. Speculating a memory write to\na linear address that has a bogus TLB mapping is possible. Normally, the\nspeculation is harmless. But for cached memory, it does leave the falsely\nspeculated cacheline unmodified, but in a dirty state. This cache line will be\neventually written back. If this cacheline happens to intersect a region of\nmemory that is not protected by the cache coherency protocol, it can corrupt\ndata in I/O memory, which is generally a very bad thing to do, and can cause\ntotal system failure or just plain undefined behavior.\n\nThese bugs are extremely unlikely, but the severity is of such magnitude, and\nthe fix so simple that I think fixing them immediately is justified. Also,\nthey are nearly impossible to debug.\n\nSigned-off-by: Zachary Amsden \u003czach@vmware.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "62c4f0a2d5a188f73a94f2cb8ea0dba3e7cf0a7f", "tree": "e85ca2d0dd43f90dccf758338764c3caa55f333f", "parents": [ "089f26d5e31b7bf42a9a8fefec08b30cd27f4b0e" ], "author": { "name": "David Woodhouse", "email": "dwmw2@infradead.org", "time": "Wed Apr 26 12:56:16 2006 +0100" }, "committer": { "name": "David Woodhouse", "email": "dwmw2@infradead.org", "time": "Wed Apr 26 12:56:16 2006 +0100" }, "message": "Don\u0027t include linux/config.h from anywhere else in include/\n\nSigned-off-by: David Woodhouse \u003cdwmw2@infradead.org\u003e\n" }, { "commit": "8f860591ffb29738cf5539b6fbf27f50dcdeb380", "tree": "4265e45c4a79d86a16cd5175a836e8c531be8117", "parents": [ "aed75ff3caafce404d9be7f0c088716375be5279" ], "author": { "name": "Zhang, Yanmin", "email": "yanmin_zhang@linux.intel.com", "time": "Wed Mar 22 00:08:50 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Mar 22 07:54:03 2006 -0800" }, "message": "[PATCH] Enable mprotect on huge pages\n\n2.6.16-rc3 uses hugetlb on-demand paging, but it doesn_t support hugetlb\nmprotect.\n\nFrom: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\n\n Remove a test from the mprotect() path which checks that the mprotect()ed\n range on a hugepage VMA is hugepage aligned (yes, really, the sense of\n is_aligned_hugepage_range() is the opposite of what you\u0027d guess :-/).\n\n In fact, we don\u0027t need this test.
